1. A cargo conveying device, comprising:
a horizontal direction conveying section configured to convey cargo in a horizontal direction, and including a transfer section at which the cargo is transferred between the transfer section and a cargo handler;
a height adjusting section configured to adjust a vertical direction height of the transfer section;
a control section configured to, at a time at which the cargo is transferred between the transfer section and the cargo handler, operate the height adjusting section to adjust the vertical direction height of the transfer section; and
a sensor provided at the transfer section and configured to automatically detect whether the cargo handler is near the cargo conveying device,
wherein
the sensor is configured to, in response to detecting the cargo handler being near the cargo conveying device, automatically detect at least a portion of a body of the cargo handler,
the control section is configured to
estimate at least one of a physique or a posture of the cargo handler based on a signal from the sensor, and
operate the height adjusting section to adjust the vertical direction height of the transfer section based on the at least one of the physique or the posture of the cargo handler that has been estimated,
the sensor includes a camera, and
the control section is configured to estimate the at least one of the physique or the posture of the cargo handler based on a position of eyes of the cargo handler in an image captured by the camera by performing image processing on the image captured by the camera.
